Abstract

Abstract A composite laminate sheet material consists of a metallic foil positioned on a congruent thick sheet of paper by means of an adhesive which can be heat cured. The composite laminate is directed via a series of rollers through a printer and a rotary die cutter where suitable geometrical sections are cut in the laminate. After the cutting operation, the sheet is directed to a series of rollers having their axes of rotation parallel to and beneath a main roller. One series of rollers directs the foil material to a first collection site, while another series of rollers directs the paper waste material to a second collection site. The rollers are so positioned that the foil material is directed to its site in a direction transverse to that of the waste material. The sections are automatically removed from the composite material unto a conveyor belt where they are directed to a heat tunnel to permanently affix the foil to the paper backing.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 378 words
A laminator and separator apparatus for making articles from a composite laminate sheet formed of a thick paper backing sheet covered by a thinner metallic foil sheet with a heat curable adhesive located between said foil and paper sheets, comprising: (a) a pair of pressure rollers through which said composite laminate sheet moves with said foil sheet facing upwards with said sheet moving in a linear path, (b) a rotary printing means in said path and operative to print indicia in discrete regions on said foil sheet, (c) a rotary die cutter for cutting a pattern in said laminate sheet with said pattern surrounding said indicia and indicative of said article, (d) a main roller located in said linear path and adapted to receive said composite sheet, (e) a conveyor roller located in said path and separated from said main roller by a predetermined distance, a conveyor belt encircling said conveyor roller, (f) a first and a second roller each having their surfaces coacting and located parallel to said main roller and positioned beneath the same with solely said thick paper backing sheet directed between said rollers, said first and second rollers of a given diameter and adapted to exert a downward force on said paper backing sheet, to cause said article as defined by said pattern to traverse said distance for directing the same to said conveyor belt, with said paper backing sheet moving downwardly towards a first collection site, (g) a guide roller of a diameter less than one half the diameter of said main roller and less than the diameters of said first and second rollers and fabricated from a material which is relatively soft as compared to said first roller, said guide roller positioned above said first roller and in contact therewith with said thin foil sheet directed solely between said guide roller and said first roller to direct said foil sheet in a path transverse to said paper sheet to a second collection site, whereby said paper sheet and said foil sheets are separated and directed to separate locations, and another coacting pair of rollers located a predetermined distance from said guide roller and within the path of said foil sheet, with said sheet of foil passing between said pair of coacting rollers.
Claim 2
Dependent Claim 378 words
A laminator and separator apparatus for making articles from a composite laminate sheet formed of a thick paper backing sheet covered by a thinner metallic foil sheet with a heat curable adhesive located between said foil and paper sheets, comprising: (a) a pair of pressure rollers through which said composite laminate sheet moves with said foil sheet facing upwards with said sheet moving in a linear path, (b) a rotary printing means in said path and operative to print indicia in discrete regions on said foil sheet, (c) a rotary die cutter for cutting a pattern in said laminate sheet with said pattern surrounding said indicia and indicative of said article, (d) a main roller located in said linear path and adapted to receive said composite sheet, (e) a conveyor roller located in said path and separated from said main roller by a predetermined distance, a conveyor belt encircling said conveyor roller, (f) a first and a second roller each having their surfaces coacting and located parallel to said main roller and positioned beneath the same with solely said thick paper backing sheet directed between said rollers, said first and second rollers of a given diameter and adapted to exert a downward force on said paper backing sheet, to cause said article as defined by said pattern to traverse said distance for directing the same to said conveyor belt, with said paper backing sheet moving downwardly towards a first collection site, (g) a guide roller of a diameter less than one half the diameter of said main roller and less than the diameters of said first and second rollers and fabricated from a material which is relatively soft as compared to said first roller, said guide roller positioned above said first roller and in contact therewith with said thin foil sheet directed solely between said guide roller and said first roller to direct said foil sheet in a path transverse to said paper sheet to a second collection site, whereby said paper sheet and said foil sheets are separated and directed to separate locations, and another coacting pair of rollers located a predetermined distance from said guide roller and within the path of said foil sheet, with said sheet of foil passing between said pair of coacting rollers.
Claim 3
Dependent Claim 19 words
The laminator and separator apparatus according to claim 1 wherein said guide roller is fabricated from an elastomeric material.
Claim 4
Dependent Claim 45 words
The laminator and separator according to claim 1 further including a heat tunnel located beyond said conveyor belt for receiving said articles as conveyed to apply heat to said articles to cure said adhesive and hence, permanently affix said foil pattern to said paper backing.
Claim 5
Dependent Claim 28 words
The laminator and separator according to claim 1 wherein said paper backing sheet moves towards said first collection site in a direction relatively perpendicular to said linear path.
Claim 6
Dependent Claim 26 words
The laminator and separator according to claim 1 wherein said foil sheet moves towards said second collection site in a direction transverse to said first path.
Claim 7
Dependent Claim 28 words
The laminator and separator according to claim 1 wherein said foil sheet is about 0.0003 inches thick, with said paper backing being between 0.010 to 0.020 inches thick.
Claim 8
Dependent Claim 17 words
The laminator and separatoring according to claim 6 wherein said foil sheet is fabricated from aluminum foil.
Claim 9
Dependent Claim 30 words
The laminator and separator according to claim 1 wherein said foil sheet is directed to said collection site at an angle of about thirty degrees with respect to the horizontal.
